My $67 sound dampening / undercoating

[josh044]

Very nice - I'd love to do some sound deadening work at some point. It would be interesting to see someone do a before and after sound level test. I wonder what fixes have the most payoff.

Deathegg - The Herculiner cures firm but flexible. It is urethane and is probably about half the durometer of roller blade wheels.

Josh044 - On Sunday night I was watching Wheeler-Dealers and they bought an old pickup to resell. The thing was loud as could be, so they bought a sound insulation kit for it. Before and after they did a sound level test and I sat there watching it going - Dang, I should have done that. I even have a good sound meter app for the iPhone.

Looks like $67 well spent. Did you have to pressure wash the dirt out before applying or just slapped it on?
Also curious about how much sound it helped block out. Damn your iPhone and that hindsight of yours! heehee.

I pressure washed it with Simple Green (and vacuumed all of the pebbles out of the leading edge of the rear wheel wells) before painting it.

I've been wanting to get rid of some of that road noise that tends to plague the Yaris, but I don't want to add a ton of weight to the car with sound deadening.

I think this might be my solution.
You think if I just do the wheel wells then it will make a difference? I probably won't be able to get to the underside of the car due to my lack of a lift.

So jealous of your garage!!! Money well spent

wow 50 lbs will slow you down guess mine must really be slow then but i cant hear anyone honking at me with the quitness i have in mine i will take the extra weight over road noise any day that is a clean under coat job i have thaught about doing that myself some day

Pennyracer - how much time did all that sound deadening work take?

[fnkngrv]

not to hijack the thread, but all I can say is that when I went and did my LSRs I noticed a difference with certain things removed.

Scott, great idea. I might have to do it myself when I have my body work done.

[pennyracer]

oh there is hours of work there not sure lost count that was the first layer i have 2 layers down and the roof is the same but i added dynamat foam layer also to make sure its nice and tight for the sound system i have in my lb :) never can go wrong with any sound deadening work to the yaris they need all you can give them

[SAV912]

Holy crap, Penny. That's looks like a few hundred bucks in sound deadening. I've done truck bed liner on the spare tire floor but that's it. I really want to Dynamat the interior like that but time is a factor. I generally don't have enough days off lined up to tear stuff apart and lay it all down and put it back together.

Did the CtScott Special over the weekend; lovin it!

[devinlamothe]

Would this stuff be the same?

Dupli-Color Bed Armor Truck Bed Liner if you can't see the link.

Also, did you have to sand the paint in the wheel well or did you just clean + paint?

That's the same stuff. The kit is more expensive, since it includes a roller, etc.

I didn't sand, but rather just cleaned very well using simple green and painted.

Awesome thanks. I am going to do this when it's nicer out to help prevent rock/salt damage. Thanks for the idea and the pics

That undercoating looks do-able even for me. The road noise on grainy pavement is tiresome alright. When you get the stuff on you how do you get it off?

Ideally you don't get it on you. Acetone works somewhat for getting it off skin. If you don't slather it on too thick it won't drip.

That lift works wonder for you! It looks great and I'm glad to hear road noise is cut down. Thanks for the awesome photos as well!
